A Class of Hyperbolic Schrodinger Equation

Yu Xuegang

Published Jan 1, 2007• 0 citations
OpenAlex

Abstract

Clifford algebra corresponds to Minkowski space. The coupling between real object particles and light quantum can be discussed by Minkowski space' s directional strangeness. A geometrical explanation for classical quantum theory is given by the introduction of Galilei transformation and Schrodinger equation into Minkowski space.

A New Interpretation of Schrdinger Cat

Yu Xuegang

Clifford is the first scientist who gives the logic relation between matter and four-dimensional space.He introduced the hyperbolic imaginary unit,which the complex space corresponds with Minkowski space in relativity theory.Using Clifford algebra,we have abstracted the hyperbolic Hilbert space from Minkowski space,and applied to quantum mechanics.Thus a new philosophical interpretation has been obtained to the move of microscopic foreign body,so much as Schrdinger cat.

Relativistic wave equations

Keith Hannabuss

Abstract One serious objection to the whole of quantum theory as we have developed it so far, is that it is inconsistent with the theory of relativity. In order to see how we may overcome this defect, at least as far as the special theory of relativity is concerned, we shall first recall some of its basic features. Shortly after Einstein’s original 1905 papers on the subject, Minkowski realized that the physical ideas could also be understood geometrically, by combining space and time into a single four-dimensional real vector space, M, whose elements we shall call four-vectors.

The 3-Sphere Instead of Hilbert Space

Alexander Soiguine

The Geometric Algebra formalism opens the door to developing a theory replacing conventional quantum mechanics. Generalizations, stemming from changing of complex numbers by geometrically feasible objects in three dimensions, followed by unambiguous definition of states, observables, measurements, bring into reality clear explanations of weird quantum mechanical features, for example primitively considering atoms as a kind of solar system. The three-sphere S3 becomes the playground of the torsion kind states eliminating abstract Hilbert space vectors. The S3 points evolve, governed by updated Schrodinger equation, and act in measurements on observable as operators.

Second-quantization and irreducible tensorial sets

Z. Rudzikas

General remarks As already mentioned in the Introduction, the exact solution of the main equation of quantum mechanics – the Schrödinger equation – lies beyond the potentialities of modern mathematics and computer technology. But a number of important inferences about the behaviour, structure and properties of a given quantum-mechanical many-particle system can be drawn without solving this equation, just by examining its symmetry properties. Symmetry concepts come about in physics in two ways. First, since any physical process occurs in a real space, we have to make use of one or another coordinate system. The isotropy and homogeneity of space make physically meaningful only those mathematical relationships that remain unchanged under rotations of the axes of the coordinate system, and that impose fairly rigorous constraints on the possible physical laws. Second, every physical object and process features a symmetry which should be taken into account by the physical theory. A common idea underlying particular forms of symmetry is the invariance of a system under a certain set (group) of transformations. The normally considered forms of symmetry are rotational symmetry, which is based on the equivalence of all directions in space, and permutation symmetry, which is caused by identical particles. The operations of the geometrical symmetry group are responsible for appropriate conservation laws. So, the rotational symmetry of a closed system gives rise to the law of conservation of angular momentum. The group of rotations of a three-dimensional space stands apart in atomic spectroscopy. This is mostly due to the high accuracy of the central field approximation, on which the entire modern theory of complex atoms and ions is based.

Introduction

Eliade N. Stefanescu

We consider the two basic theories of the standard physics: (1) the theory of relativity, as a four-dimensional time-space description of our universe, with the invariance of the time-space interval which leads to the Lorentz transformation, and (2) quantum mechanics, based on the Schrödinger equation, with a solution called wave function. However, we find that this equation is very unsatisfactory, describing fully unlocalized free particles, any initially localized particle rapidly spreading in space, in disagreement with the fundamental Hamilton equations. In agreement with the Hamilton equations, we describe a quantum particle by propagation wave functions in the coordinate and momentum spaces, with the Lagrangian in the time dependent phase instead of the Hamiltonian coming from the Schrödinger equation. With the relativistic Lagrangian, we obtain wave functions describing invariant distributions propagating in space.

On a New Basis for a Generalized Clifford Algebra and its Application to Quantum Mechanics

Alex Granik, Marvin Franklin Ross

A generalized Clifford algebra is formulated in terms of a simple Euclidean carrier space. Using this space the eigenvalues, shifting operators, and the Casimir operator are easily derived for a few selected quantum mechanical problems.
